So, my ex and I were in a tumultuous relationship for over 4 years. The last year of the relationship we lived together as 'friends.' umm...yeah, purgatory. I am bi. She is lesbian. It was her first relationship and my first same-sex relationship. I wanted to have an exploratory/physical relationship and she wanted more. I agreed. Now, its 4 years later and we finally get our own apartments. Within 2 weeks of me moving into my new place she tells me she is hooking up with a classmate, but Its not a committed relationship. She's just have amazing sex and it better sex than we had... 1) Thats the relationship I wanted the whole time. 2) I've been really depressed because I tried to make it work and sacrificed a lot for the relationship. 3) I agree we had a very boring sex life. Now, I also want to have that fun exploratory sex I was looking for 4 years ago. The predicament: My ex always seemed like a prude, but she seems to have come out of her shell. Do I try to have a threesome with her considering she's in this new open relationship? Or do I not risk my potential hurt feelings of being turned down and/or whatever feelings come up during the act? Lastly, am I being that crazy ex!? NO!
